Indiana State had too many turnovers in Hawaii one night after a thrilling overtime win.

The Sycamores had 17 turnovers and only seven assists on Sunday in a 62-55 loss to No. 18 San Diego State in a second-round game at the Diamond Head Classic tournament.

Indiana State lost despite coming back several times from short runs by the Aztecs, tying the game or flipping the lead rather than allowing San Diego State to pace the game.

RJ Mahurin had 15 points, and Manny Arop had 13 for the Sycamores (6-4).

"We knew it was going to be tough, and coming in we'd have to grind and grind and grind on them," Mahurin said. "I thought we did that, and that put us out there right at the end."

Neither team established a clear advantage beyond a few key runs until San Diego State gained control late.

San Diego State pulled ahead for good during a seven-point run that included five straight points from Chase Tapley. With less than five minutes to play, Tapley drove to the basket and was stopped by Jake Odum, who was called for a flagrant foul. Tapley made two free throws, and then a quick 3-pointer on the ensuing possession to give the Aztecs a 51-44 lead.

"Every trip down the floor seemed like a big possession," San Diego State coach Steve Fisher said. "Both teams came up empty at times."

Franklin was one rebound shy of his career high, set last season against Colorado State. Xavier Thames had 12 points.

The Aztecs went on a 9-1 run midway through the first half to take a 20-13 lead with just under eight minutes left, capped by a three-pointer from Tapley. But the Sycamores pulled to within 28-25 at halftime.

Mahurin hit a 3-pointer from the right wing three minutes into the second half to give Indiana State a 32-31 lead.

The game had five ties and six lead changes.

"They made us guard for 35 seconds and make baskets as the shot clock was going out," Fisher said. "The shots that were falling like raindrops (Saturday) weren't going in."

After the game, Indiana State coach Greg Lansing was visibly upset as he looked at the box score while waiting for an interview with his team's radio broadcasters.

San Diego State shot less than 24 percent (4 of 17) from 3-point range, and 64 percent (18 of 28) from the free throw line.

"We regained our composure, took a deep breath and allowed defense to create some offense and make free throws down the stretch after missing so many early on," Fisher said. "It wasn't the prettiest of games, but hard fought by both teams."
